腰椎管狭窄症椎板减压术后脊柱失稳相关因素研究

Retrospective Analysis of Related Factors of Spinal instability after Lumbar Disc Decompression in Patients with Lumbar Spinal Stenosis

对于腰椎管狭窄症(lumbarspinalstenosis,LSS),无论是单纯椎板减压术还是植骨融合内固定术,一贯坚持彻底减压的原则,以减轻对神经根和椎管的压迫。但减压的同时也间接破坏了脊柱生理性稳定系统,可能造成的脊柱滑脱等术后并发症。论文分析了术后可能影响脊柱稳定性的因素。认为LSS术前应该结合病史,根据"症状+体征"原则,采纳Hansraj分型,制定个性化的手术方案,在充分减压的同时充分兼顾脊柱的稳定性,以降低术后脊柱失稳的发生率,提高术后康复率。

For lumbar spinal stenosis （LSS）, whether it is a simple laminectomy or bone graft fusion fixation, the prin- ciple of complete decompression has been adhered to, so as to relieve the compression of nerve roots and spinal canal. However, decompression also indirectly destroys the physiological stability system of the spine and may cause postopera- tive complications such as spondylolisthesis. The paper analyzes factors that may affect spinal stability after surgery. It is believed that LSS should be combined with medical history before surgery. According to the principle of ＂symptoms＋signs＂, the Hansraj classification should be adopted to formulate a personalized surgical plan to fully take into account the stabil- ity of the spine while reducing the risk of postoperative spinal instability.
